The tow hook holes in the bumper had to be elongated with a die grinder quite a bit, then one hole had to be popped in the frame on each side to make it work. Wasn't a big deal but kinda surprised they were that far off. I almost started to wonder if the holes were intended for the tow hooks or not. It doesn't look as nice with the tow hooks on, but the driver side saved my ass big time the very next day after I installed it. It's also 4 more bolts holding the bumper to the frame. So I guess they can stay.
I thought RPG was coming up with a piece to hold the valence. I might wait for them or build my own. Mine isn't sagging yet.
